My cat chases his tail all the time, but the funniest part is when he gets a large piece of food (like a piece of pizza crust or something) and sits still with it in his mouth growling while looking at his tail out of the corner of his eye. Like his tail is going to steal the food!

i don't have a dog but my kittys do it all the time, its like they are pretending its prey or something, haha soo cute

I think dogs do it because it's a way of playing or clearing their tails of fleas/ticks before cleaning them with their tongues. A vet told me that - But I'm somewhat dubious...

I do know that whenever I had cats & some idiot thought it was funny to tie something to their tails... It literally drove the poor thing crazy. The cat would go in circles to rid themselves of whatever was on their tails. It was NEVER FUNNY but CRUEL & I would always let them know it... & keep them AWAY from my cats.
